I'm willing to bet most of the songs on DYD will see a single release. Might be the end of 2011 by the time we see a couple of them though. Don't forget it took a year to see Daydream get a single release. I'm hoping Markus doesn't wait until CLHR150 to release 65.4 Hz.
Hopefully by Coldharbour Day 2011, we'll have all the goodies from DYD released as singles.
